For a custom board with i.MX6s or i.MX6Q we need to rotate the display to portrait. According to the i.MX6 reference manuals, the GPU supports the rotation, but there is an older post in the community:
which tell that the vivante driver is not supporting rotation. This post is quite old, so my question: Does the vivante driver support imx6-gpu rotation meanwhile?
Best regards

Hi Joan,
thank you for your response., but which “enclosed file” do you mean. I did not find an attachment.
Meanwhile we have made some investigations and it looks to me, that the vivante driver does not use the GPU-Rotation feature and so does not use the hardware acceleration of the GPU. In the Xorg-log file we see this: (EE) AIGLX: reverting to software rendering
which makes us assuming the vivante driver finally uses the /dev/fb0 device and not the iMX6 GPU.
Is this true?
Thank you in advance and best regards
Elmar
